KYN28A 12kv Switchgear Is On Production

KYN28A 12kv switchgear is on production.

The common 10kV high-voltage switchgear in China is the KYN28A-12 switchgear, and its model letter has been marked with its meaning.

K: Refers to the structure of the switchgear.

Y: It means that the circuit breaker can be removed and drawn out.

N: Indoor or indoor use.

28A: refers to the design number, which is convenient for distinguishing and remembering.

12 (24): It means that this switchgear can only be used in the voltage level of 12 (10) kV or 24 (20) kV.

Let’s first understand its full name: indoor AC metal armored mid-mounted switchgear, which is referred to as 10kV switchgear or 10kV high-voltage cabinet by industry insiders. The appearance is as follows:

KYN28A indoor AC metal armored central switchgear is suitable for three-phase AC power system with rated voltage of 12KV, 24KV and rated frequency of 50(60)Hz. For receiving and distributing electrical energy, control, protection and circuit monitoring.

KYN28A-12 12kv High Voltage Switchgear Structure

The high-voltage switchgear is composed of two parts: the cabinet body and the middle-mounted withdrawable part (ie the handcart). The cabinet is divided into four separate compartments, the enclosure is rated IP4X, and each compartment and circuit breaker compartment is rated IP2X when the door is opened. This switchgear can be installed, debugged and maintained from the front, so it can be arranged back-to-back and installed against the wall.

As far as the switchgear is concerned, the incoming or outgoing cabinet is the basic cabinet solution. In addition, there are other solutions for installing fixed load switches, vacuum contactor handcarts, and isolation handcarts. The structure of the switch cabinet: shell partition, circuit breaker room, circuit breaker handcart, busbar room, relay instrument room, interlock device to prevent misoperation, pressure relief device, etc.
